Abstract

With the simultaneous presence of positive and negative components both in the permittivity tensor ɛ_ij and in the tensor of magnetic permeability μ_ij, the propagation of an electromagnetic wave in optically homogeneous anisotropic media, and in periodically inhomogeneous media with a spiral structure is considered. It is shown that depending on polarization, such media exhibit the properties of both dextrorotatory and levorotatory substances. It is shown also that the medium with a spiral periodic structure may have the property of total diffraction reflection of the wave of any polarization. In the case of the presence of different signs of components of ɛ_ij and μ_ij in the spiral medium, it is revealed that two regions of diffraction reflection are formed, corresponding to the two waves with circular polarization with mutually opposite rotation of the polarization.

同时具有左右物质性质的光学介质的偏振和衍射特性

摘要

在介电常数张量_ij和磁导率_ij的张量中同时存在正负分量的情况下，考虑了电磁波在光学均质各向异性介质和具有螺旋结构的周期性非均匀介质中的传播。结果表明，取决于极化，这种介质同时具有右旋和左旋物质的特性。还显示出具有螺旋周期结构的介质可以具有任何偏振波的全衍射反射的特性。在的ɛ部件的不同标志的存在的情况下_IJ和μ _IJ 在螺旋形介质中，揭示出形成了两个衍射反射区域，分别对应于两个圆偏振且偏振旋转彼此相反的波。
